摘要

当光纤光栅传感器上的温度或应力发生变化时

布拉格反射波长也随之发生漂移

根据这个漂移量便可判断待测量大小

因此

人们提出了许多解调方法。文章论述了几种常用的光纤光栅传感器信号解调方法

分类评述了这几种方法的工作原理和性能

分别给出了其典型的实验原理图

并对其优点和缺点进行了分析比较。

Abstract

When the temperature or stress on the Fiber Bragg Grating（FBG） sensor is changed

the Bragg wavelength will shift accordingly. The measurand can be assessed by detecting the shift.Many signal demodulation methods for detecting the shift of the FBG sensor have been proposed.In this paper

several commonly used ones are described

their operating principles and performances reviewed

their typical experimental schematic diagrams given and their merits and demerits analyzed and compared.
